Bottom bite holds on Chesapeake structure as bay cools
Chesapeake Bay water sits at 67.6°F as of this morning's NOAA CO-OPS reading at station 8570283, right in line with the fall cooldown. Regional DE/MD/Chesapeake reports from The Fisherman show the bottom bite carrying the week: boats working ocean structure came back with black sea bass, per Hook 'em and Cook 'em, while Old Inlet Bait and Tackle noted bluefish hitting metal lures on the incoming tide. Smith's Bait Shop reported boats on Delaware Bay were kept in port by rough seas over the same stretch, so most of the week's action came from the crews that found a weather window to get out to structure.

With water temp holding in the upper 60s, expect the structure bite on black sea bass to stay the more dependable play into the weekend, since that species tracks cooling bottom temps toward deeper, harder bottom rather than shutting down outright. Bluefish should keep showing on incoming water wherever bait gets pushed through inlets and channels, the pattern Old Inlet Bait and Tackle described, so timing a trip around the push of the tide is the practical move right now.
Today's new moon means stronger-than-average tidal exchange for the next several days, which typically sharpens the bite window around the moving water rather than the slack. Anyone planning around the coming weekend should lean into that incoming stage rather than fishing the full tide cycle evenly. If the rough seas that sidelined Delaware Bay boats clear, expect more direct reports to follow from boats able to reach ocean structure again.
Context
This is a normal point in the Chesapeake's fall transition: water in the upper 60s is typical for early-to-mid October, with bottom species like black sea bass and tautog typically taking over as the headline fishery from inshore structure while bluefish continue working the moving tides until temperatures push them further along their fall migration. Nothing here points to an early or late season, just the standard shift from summer patterns toward the deeper, structure-oriented fall bite. Anglers should check current state regulations before harvesting, since seasons and size limits can shift this time of year.
